With Rooney on his own up front v the Swiss, I see the most likely source of goals being Joe Cole and Stevie G for two reasons.
Firstly, Rooney will find himself furthest man forward and holding the ball up (no doubt with two defenders at his back). Nice positions to either lay it back to the midfielders for a shot or for them to bomb past him and wait for him to pick them out with a pass.
Secondly, England will be attacking wide down both flanks. Ideal for balls to be pulled back to the edge of the box for SG or JC or for balls crossed into the box to be headed out to the waiting SG on the edge of the box.
Both can be backed at 13/5 at anytime JC with
Coral and SG with
